Saving NAV favorite with Way Point(s)

Newbie here.

Is there a way to save a specified route using way points in between the final destination? I have a specific route I like to drive to avoid traffic, etc., and would like to save the entire route as one favorite. Best I've been able to do is save way points as favorites and then add them to to my final destination route. Seems I have to manually do this every time I take this particular route.

Is there a way of saving the way points as part of the destination favorite? Yes, I know I have the route memorized but I wanted this route in the navigation system just in case I was zoned out and missed an exit, etc. The other alternative is Android Auto using Google but not sure I want to at this point. Rather use the Mazda NAV.
